I meant "millimeter", not centimeter! The material is very thin. I think that's why it failed, it was too flimsy. I went back out and looked at the bed slides, and 1/4th inch seems like it's going to be too wide, so your idea about the tape might be the way to go. There's already an aluminum "L" that the bed is attached to, so I could put the tape on there. On the side, outside of the "L", there is pressed board glued onto the "L", the tape would also have to go on top of that. I think it's worth a try.

Thanks.
